[Bug]: Versions are broken on encrypted mounts of local or external storage #40029
Description
⚠️ This issue respects the following points: ⚠️
- This is a bug, not a question or a configuration/webserver/proxy issue.
- This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
- Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
- I agree to follow Nextcloud's Code of Conduct.
Bug description
I use server-side encryption for mounts of some local mounted folders, but I also tested it with an FTP mount. If I sync files to these places, everything works well except versions. Try to access or to reset to an older version of the file end up in not found errors.
For the non encrypted space, everything works well.
Steps to reproduce
- Activate server-side encryption for external storages
- As an Admin create a local or external mount and give at least one user access to it.
- Put some files in this and edit them, update them, sync them. See that versions are created.
- See at versions tab on the sidebar that only the current version is accessible. Older ones are broken.
Expected behavior
The versions should work like it does on the local storage.

No errors have been found.Nextcloud Logs
Empty regardless of the log level if I reproduce this error.Additional info
The browser or operating system is not relevant. Tried it with Firefox on Linux and Windows 11 and also with Google Chrome on Windows. But I think it is a server-side problem.

Hi @nils-one - Thanks for the report. Just a couple clarifications to make sure I understand the situation:
So both scenarios are External Storage, but one is using the Local backend and the other the FTP backend? i.e. https://docs.nextcloud.com/server/latest/admin_manual/configuration_files/external_storage_configuration_gui.html#available-storage-backends
Is that accurate?
Non-encrypted meaning if you disable encryption on either of the External Mounts or do you mean files simply stored in your configured
datadirectorywithout any mounting involved?Thanks again for your report.

Sorry for the confusing description. I try to clarify:
Both scenarios where version are not working are external mounts. One with local backend and one with FTP backend. With encryption on.
If I store the file on the
datadirectorywithout mounting involved and without encryption, it works.If I switch on encryption for
datadirectorytoo, versions also work.What I've not tested yet is using mounting without encryption, as I don't want to switch encryption completely off (as a lot of files would be affected). But maybe I can set up a test instance later.
